1. Grab the other three files from this zip into a directory or onto your desktop.
2. Drag xlEntryPointCSB.bas into the VBA Project of Personal or the workbook of your choice.
3. Drag frmShowBinary.frm into the same project. It will get what it needs from frmShowBinary.frx automatically.
Then you can delete all three files.
Back in Excel, do Ctrl+Shift+B (mentally attached as Conveniently Show Binary) to show the cell's contents.
